More FUN with Swamps

You know you have a problem when half of the photos on your memory card are of teeny tiny black beetles. I don’t know if I’ll ever be able to tell the difference between Tomicus minor and Tomicus Piniperda.

I do know that a swamp is a great place to find lots of insects, including those that bite yours truly like mosquitoes and ticks. I learned that the latter starts coming out to bite at 5 C.

These birch were in the swamp we were studying. Birch don’t grow in swamps naturally, but these got the death sentence from park managers. Most of Sweden’s forests are so well managed for wood production that there isn’t enough dead wood, which is an important habitat for insects. So the park managers built a dam and flooded this area, which killed the birch by depriving their roots of water.
